| The current thesis proposes the definition and development of a knowledge-based system to generate aircraft components assembly line models during the conceptual phase of the product life cycle. With this objective, the definition of a formal activity model to represent the design of assembly lines during the conceptual phase is proposed; such model considers the concurrence with the product design process. Associated to the activity model, a data structure model is defined to support such process. Both models are the basis for the development of a proof of concept application within the environment of the commercial CAX-PLM system CATIA v5. The generated assembly line models integrate the three basic structures defined in the proposed model: product, processes and resources. The generated models are ?As Prepared? structures based on ?As Planned? structures derived from ?As Designed? structures. Each generated model is evaluated in terms of four basic estimates: maximum dimensions of the product node, transport distance and transport mean to be used, total execution time and total cost. The assembly line models generation is made in concurrence with the product design function. Therefore, it provides the opportunity to influence on it and allows including manufacturing and assembly requirements early in the product life cycle, which gives a clear competitive advantage. The development proposed in this Thesis allows setting the foundation to carry out further developments with the aim of assisting designers during the conceptual phase of the assembly line design process. The developed prototype application shows the feasibility of the conceptual proposal presented in the Thesis. | |
